Gaming Rig Upgrade: motherboard + cpu (4770k or 4930k) ..... + graphics card , at a later date)

I currently have an i5 3570k @4.7ghz with an ASrock extreme 4 mobo. and dual sli gtx670 2gb,(all watercooled) running a 5760x1080 120hz surround display.
I want to purchase a 3rd gtx670 which will require a new Mobo.

--Firstly, Will my 2gb Graphics cards limit me with the big resolution?

--Im replacing the motherboard and cpu soon!, should i go for a 4770k($385) with a MXPOWER Board(~$400) (to get 3way sli support) or a 4930k($669) with an Asus rampage IV formular (~$420) or an ASUS P9X79-LE (~$250) or a different motherboard(I'd like to get a decent Overclock)?

Also! I need room to fit my sound card on the mobo(pci. so the onboard sound features on the rampage are kind of a waist, or is it worth the extra cash for the over clocking potential?

My needs are mostly gaming, and i want to achieve high frame rate (70-80fps) on medium-high settings

  1. Yes 2GB will definitely be a limiting factor sometimes at that resolution. I do not recommend going for 3 cards, but if you do, you must go with a X79 motherboard or the 3rd card will be wasted running at 4x. The X79 offers enough PCI lanes for the 3 cards to run at 100%.

    But honestly, you are better of selling you two 670s and getting something new.
  2. I completely agree with CTurbo that the 2gb would be definitely be a bottleneck at that high resolution. What u can do is sell the two 670's and buy pair of 780Ti's/290X's.

    thanks for the quick reply!
    What if i avoided settings like MSAA x8? would that be enough to stop the bottle necking? im playing games like crysis 3 and farcry 3, and watchdogs when its released.
    Also with the 4770k I can get a PLX board which will alow me to run 4 cards at 8x.
    the motherboard is the next upgrade( as im using it to build a family computer) would you recomend going the x79 mobo with the 4930k (it would be worth it if it gets me longer before i need an upgrade) , or 4770k with or without the expensive PLX board.

    would the 3gb models of those cards also cause me issues?
    i could go for the 4gb 770 or 6 gb 780/780ti?
  5. You could always get the i7 4820k and X79 motherboard to keep costs down a little. I still don't think there is any scenario in which I would attempt to run three 670s together though. I would want to spend so much money and then have to worry about a bottleneck. I'm sure you could get good money for your used 670s.
  6. Any combination of two 780s, 780tis, 290s or 290xs would be really good. 3GB vram minimum.
  7. i looked on ebay.com.au and ill could get around $200 per card, is that decent?
    i payed ~460-500 each for them new
  8. $200 per card is not bad at all. How long ago did you buy them?
  9. i got one nearly 2 years ago and the other 6-12 months after that
  10. Well you can keep them until they no longer perform to your standards, and then get a new GTX8xx when they come out.
  11. think that's what ill do! thanks for the advice CTurbo.

    Do you have any advice on cpu/motherboard combos?
    i probably wont do 3 way sli.....maybe if i can pick up a real cheap 670(just to test it out) ,
    but it may be an option way down the track >3 way sli 880??< ( if the sli technology improves in the years to come).
    if i went for the x79 board id put in the extra money to jump up to the 6 core 4930k, i wouldnt bother with the 4820, i think the 4770k with PLX board would be better than the 4820.

    If i go for the 4930k id like it to last me a couple of gpu upgrades( Is that possible? ). or am i going to get similar longevity out of the 4770k?

    let me know if that all makes sense :P
  12. Why build a family pc? You already have one. Pull the WC, turn back the speed to 4.2-4.3, slap in a 212 EVO and call it done. Sell the 670 blocks and put the stock coolers back on. Now you have WC for new build. Start from scratch. You're getting everything but psu,case and storage anyways, and that's cheap comparatively.

    Dual 780ti's will blow the socks off trip 670's, and I believe Asus has either 780 or 780ti with 6Gb vram, which basically makes the titan obsolete.

    Any current Intel i5 or i7 will last for several generations for gpus. Your 3570k is good to go for several more years too. You don't NEED to upgrade it at all. The 4820k and 4770k will perform similarly even though the 4820k is Ivy Bridge. You could always wait for Haswell-E to come out. I believe that will come with a new platform as well.
  14. the family PC already exists, im just throwing out its crappy motherboard + cpu and putting the one from my rig in to replace it.
    I cant afford to replace my entire system at the moment, so im going to do it in chunks ( motherboard + cpu ) then Graphics in a few months.
    I just cant decide what CPU and motherboard combo to get, since im catering to a gpu sett up that i will not be buying for some time. something like 2-3 Sli 880~
    I made the mistake last time of buying a cpu (3570k) that couldnt handle sli 670's on 1960*1080 and a graphics card with not enough mem to handle 5760x1080. -.-
    so when i get a new cpu ill probably play a lower resolution till i get new cards.

    when do you believe the haswell-E will be released? because either way i need to upgrade the family PC relatively soon (locks up alot...) I wouldn't be upgrading if i didn't need to buy a new board anyway.
    Im guessing the 4930k wont get me much more life than the 4820/4770k?
    Thanks for all the help so far!
  16. I think they are set for the beginning of the 3rd qtr which would be sometime next month. They will have DDR4 support too!
  17. Sounds good, will they be inflated in price when they first come out and drop in the months shortly after?
    Does DDR4 mean much for gaming?

    i looked futher into it on
    http://thepcenthusiast.com/intel-haswell-e-processors-core-i7-5960x-i7-5930k-i7-5820k/
    "The Core i7-5930K will have 2 x16 + 1 x8 configuration, similar with the Core i7-5960X; meanwhile the Core i7-5820K will only support 1 x16 + 1 x8 + 1 x4 multiple graphics card configuration."
    Does this mean that the 5820k is not 3 way sli compatible? can the x16 be split?
    is there any restrictions on the 4820 like they are expecting for the 5820k?
